To make V-Window settings
1. From the Main Menu, enter the GRAPH mode.
2. Press (V-WIN) to display the V-Window setting screen.
Rectangular coordinate parameter
Xmin/Xmax ... Minimum/maximum
Xscale ... Spacing of
Xdot ... Value that corresponds to one
Ymin/Ymax ... Minimum/maximum
Yscale ... Spacing of
Polar coordinate parameter
T min/T max ... Minimum/maximum T, values
T ptch ... T,
3. Press to move the highlighting and input an appropriate value for each parameter,
pressing after each.
• {INIT}/{TRIG}/{STD} ... V-Window {initial settings}/{initial settings using specified angle
unit}/{standardized settings}
• {STO}/{RCL} ... V-Window setting {store}/{recall}
After settings are the way you want them, press
setting screen.
• Pressing without inputting anything while
V-Window setting screen.
V-Window Setting Precautions
• Inputting zero for T ptch causes an error.
• Any illegal input (out of range value, negative sign without a value, etc.) causes an error.
• When T max is less than T min, T ptch becomes negative.
• You can input expressions (such as 2 ) as V-Window parameters.
• When the V-Window setting produces an axis that does not fit on the display, the scale of
the axis is indicated on the edge of the display closest to the origin.
• Changing the V-Window settings clears the graph currently on the display and replaces it
with the new axes only.
• Changing the Xmin or Xmax value causes the Xdot value to be adjusted automatically.
Changing the Xdot value causes the Xmax value to be adjusted automatically.
• A polar coordinate (
the V-Window cause the T ptch value to be too large, relative to the differential between
the T min and T max settings. If the settings you make cause the T ptch value to be
too small relative to the differential between the T min and T max settings, on the other
hand, the graph will take a very long time to draw.
